New Guinea impatiens plant named `Kimpque`

ABSTRACT

A new and distinct cultivar of New Guinea Impatiens plant named `Kimpque`, characterized by its small and numerous scarlet-colored flowers; very compact, rounded, mounding, somewhat upright, dense and bushy plant habit; short internodes; freely branching habit; and small dark green leaves.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of New Guinea Impatiens plant, botanically known as Impatiens hawkeri, and hereinafter referred to by the cultivar name Kimpque.

The new cultivar is a product of a planned breeding program conducted by the Inventor in Gensingen, Germany. The objective of the breeding program was to develop compact varieties with numerous small flowers, early-flowering, uniform plant habit, attractive flower and foliage colors and good flower form.

The new cultivar originated from a cross made by the Inventor of the cultivar Kique (not patented), as the male, or pollen parent, with the propietary selection identified a B 882 as the female, or seed parent. The cultivar Kimpque was discovered and selected by the Inventor as a flowering plant within the progeny of the stated cross in a controlled environment in Gensingen, Germany, in April, 1995. Asexual reproduction of the new cultivar by terminal cuttings taken at Gensingen, Germany, has shown that the unique features of this new Impatiens are stable and reproduced true to type in successive generations of asexual reproduction.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and are determined to be the unique characteristics of `Kimpque`. These characteristics in combination distinguish `Kimpque` as a new and distinct cultivar:

1. Small and numerous scarlet-colored flowers.

2. Very compact, rounded, mounding, dense and bushy plant habit.

3. Short internodes.

4. Freely branching habit.

5. Small dark green leaves.

Plants of the new New Guinea Impatiens are more vigorous and have larger leaves and more orange flower color than plants of the male parent, `Kique`. Compared to plants of the female parent, B 882, plants of the new New Guinea Impatiens are less vigorous and have smaller and redder flowers.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall apperance of the new cultivar, showing the colors as true as it is reasonably possible to obtain in colored reproduction of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which more accurately describe the actual colors of the new New Guinea Impatiens.

The photograph at the top of the sheet comprises a side perspective view of a typical plant of `Kimpque`.

The photograph at the bottom of the sheet comprises a close-up view of a typical flower and leaves `Kimpque`. Flower and foliage colors in the photographs may differ from the actual colors due to light reflectance.

DETAILED BOTANICAL DESCRIPTION

The cultivar Kimpque has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature and light intensity, without, however, any variance in genotype. The following observations, measurements and comparisons describe plants grown in 10-cm pots in Encinitas, Calif., under commerical practice in a fiberglass-covered greenhouse with day temperatures ranging from 23 to 29° C. and night temperatures ranging from 16 to 18° C. and light levels of about 3,000 footcandles.

In the following description, color references are made to The Royal Horticultural Society Colour Chart except where general terms of ordinary dictionary significance are used.
